Description

Technical Field

[0001] The invention relates to the technical field of artificial stone processing, in particular to a molding press for artificial stone manufacturing. Background Art

[0002] Resin-type artificial stone is made of cement and stone powder or other inorganic fillers in a certain proportion, and then processed through processes such as mixing and molding. Artificial stone is inexpensive, has low water absorption, high compressive strength, and is more resistant to pollution than natural stone. It has good durability and aging resistance. Most artificial stones are mass-produced by manufacturers, but some construction teams will produce them on-site according to the special conditions of the construction site.

[0003] Considering that only a small number of small artificial stones are needed on the construction site, if a special shape is required, it is too wasteful to cut large artificial stones. The existing technology usually makes it difficult to control the size of artificial stones when molding them. If molding of a specific size is required, it is necessary to first select a suitable mold and pressing plate; considering that the artificial stone production process needs to wait for solidification before it can be completely molded, the artificial stone will transfer heat to the equipment during the molding process, thereby causing the equipment temperature to rise. The increase in equipment temperature will not only slow down the molding speed of the artificial stone, but may also cause the equipment to accumulate too much heat and cause damage. Summary of the invention

[0004] The object of the present invention is to provide a molding press for manufacturing artificial stone to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a molding press for artificial stone manufacturing, comprising a mold body and an equipment body, the top of the mold body is slidably connected with a clamping heat dissipation mechanism, the mold body is used for molding artificial stone, the middle of the inner walls on both sides of the mold body corresponding to each other are provided with fixed grooves, and each two groups of fixed grooves are on the same side, and the inner wall of each group of the fixed grooves is fixedly connected with a limiting mechanism; the inner wall of the equipment body is fixedly connected with a vibration mechanism; the top of the inner wall of the equipment body is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected with a driving press; the bottom of the driving press is clamped with a pressing plate; The clamping heat dissipation mechanism includes a clamping plate, and two groups of clamping plates are symmetrically arranged; the bottom of the clamping plate is slidably connected to the inner surface of the mold body, and the side of the clamping plate away from the clamping plate is evenly fixedly connected with a clamping spring, and the end of the clamping spring away from the clamping plate is fixedly connected to the inner wall of the mold body; the part of the clamping plate that exceeds the top surface of the mold body is an inclined surface, and the side of the clamping plate away from the clamping plate is fixedly connected with a push plate; the side of the mold body away from the clamping plate is fixedly connected with a circulating water tank; the outer wall of one side of the circulating water tank is penetrated by the push plate, and the outer wall of the push plate is sealed and slidably connected with the inner wall of the circulating water tank at the penetration point, and the side of the push plate close to the circulating water tank is a triangular surface; A throttling block is slidably connected to the surface of the triangular surface; through holes are provided from the upper end surface to the lower end surface of the throttling block, and there are multiple groups of through holes, and one side of the throttling block is slidably connected to the inner wall of the circulating water tank; oblique slide grooves are provided on the corresponding two sides of the inner wall of the circulating water tank, and the angle of the oblique slide groove is consistent with that of the triangular surface, and the inner wall of the oblique slide groove is slidably connected to one end of the throttling block; a heat dissipation water tank is fixedly connected to the side of the circulating water tank away from the clamping plate; an impeller pump is fixedly connected to the bottom of the inner wall of the heat dissipation water tank; a water inlet is provided on the outer wall of the circulating water tank away from the clamping plate, and a water outlet is provided on the same side of the circulating water tank, and the water inlet and the water outlet are connected to the inner wall of the heat dissipation water tank.

[0006] By adopting the above technical solution, when in use, first replace the appropriate pressing plate, and drive the pressing plate downward by driving the press to shape the artificial stone. When the pressing plate moves downward, it will push the clamping plate to move outward. At this time, the artificial stone is still a fluid. At this time, the artificial stone is extruded and formed by the pressing plate, and the heat is transferred to the mold body through the artificial stone to reduce its temperature so that it can be formed faster. When the temperature of the mold body is too high, it will be cooled by the water inside the circulating water tank to ensure constant temperature and will not affect the molding speed of the artificial stone.

[0007] Furthermore, the vibration mechanism includes a driving motor, the side of the driving motor away from the mold body is fixedly connected to the equipment body, the output end of the driving motor is fixedly connected to an eccentric wheel; an eccentric block is provided at the bottom of the eccentric wheel, a traction link is hinged on the outer wall of the eccentric block, and the eccentric block plays a positioning and limiting role for the traction link; a driven plate is hinged on the inner wall of the end of the traction link away from the eccentric block; a traction block is slidably connected to the inner wall of the driven plate; a vibration plate is fixedly connected to the top of the traction block; the bottom of the vibration plate is fixedly connected to a limit strip, and two groups of limit strips are symmetrically arranged, and the adjacent sides of the limit strip are slidably connected to the two sides of the driven plate; the bottom of the mold body is fixedly connected to A sliding block is connected; the bottom of the vibration plate is slidably connected to the bottom of the inner wall of the equipment body, the top of the vibration plate is slidably connected to the bottom of the circulating water tank, and the top of the vibration plate is provided with an impact groove; the inner walls on both sides corresponding to the impact groove are slidably connected to the outer wall of the mold body, and the inner walls on the other two sides of the impact groove are fixedly connected with impact blocks, and there are multiple groups of impact blocks, and the impact groove and the same two sides of the impact block are fixedly connected with buffer springs, and there are multiple groups of buffer springs, and the end of the buffer spring away from the impact groove is fixedly connected with a buffer plate; a positioning groove is provided at the bottom of the impact groove, and the inner wall of the positioning groove is slidably connected to the outer wall of the sliding block; the side of the buffer plate away from the impact block contacts the outer wall of the mold body.

[0008] By adopting the above technical solution, the driving motor is started to make the vibration plate reciprocate, and the impact block repeatedly impacts the buffer plate through the reciprocating motion, and the force is transmitted to the inside of the mold body through the buffer plate. At this time, vibration can be performed, and the bubbles inside the artificial stone can be removed by vibration. The vibration generated by impacting the mold body can avoid the influence of excessive vibration on the molding of the artificial stone, and the vibration can be transmitted to the inside of the artificial stone more evenly through the mold body. After the vibration ends, the buffer spring will push it back to the original position to ensure accurate positioning of the pressing.

[0009] The cam is connected with the locking plate to move the locking plate, and the locking plate is connected with the locking plate to move the locking plate in a direction of rotation and the locking plate is locked to the locking plate by the locking cam.

[0010] The above technical solution is adopted, considering that the size of the artificial stone can be controlled by squeezing the clamping plate by the pressure plate, but when the pressure plate squeezes the artificial stone, the artificial stone may be squeezed out to both sides due to the force, and at this time a thrust may be applied to the clamping plate. When the clamping plate is subjected to force, it will move outward. At this time, the artificial stone will flow to the gap, thereby affecting the molding.

[0011] In order to prevent the flowing artificial stone from generating thrust on the clamping plate and affecting the molding of the artificial stone, when the pressure plate moves downward, it will come into contact with the moving block and squeeze the moving block to move toward the inside of the limit shell. The limit plate can be moved to the outside of the limit shell through the hinge connection between the moving block and the driven connecting rod. When the limit plate and the driven block come into contact, the friction force will prevent the movement of the driven block. Since the driven block will move with the clamping plate, the movement of the clamping plate can be prevented when the driven block is prevented. When the pressure plate moves out, the moving block will be reset under the force of the reset spring, and the limit plate will be reset, and the driven block will move with the clamping plate.

[0012] Furthermore, a first ratchet is provided on a side of the limiting plate close to the driven block; and a second ratchet is provided on a side of the driven block close to the limiting plate.

[0013] By adopting the above technical solution, when the limiting plate and the driven block are in contact, the contact area is increased by the mutual meshing of the first ratchet and the second ratchet, and the driven block is clamped by the characteristics of the ratchet.

[0014] Furthermore, the material density of the throttling block is smaller than that of water, and the inside of the throttling block is hollow.

[0015] By adopting the above technical solution, the density of the throttling block is smaller than that of water and the throttling block is hollow. When the throttling block is inside the circulating water tank, the buoyancy of the water will lift the throttling block. Since the throttling block only achieves the throttling effect, the sealing of the throttling block blocking the water inlet is not important. When the water inside the circulating water tank decreases, the throttling block will still be on the top of the water and achieve the throttling effect. Through throttling, the thermal expansion of the water inside the circulating water tank can be realized to circulate the water.

[0016] Furthermore, a buffer pad is fixedly connected to the inner wall of the driven plate, and there are two groups of buffer pads; a first shock-absorbing pad is arranged on the surface of each group of impact blocks close to the buffer plate; and a second shock-absorbing pad is arranged on the surface of the buffer plate close to the mold body.

[0017] By adopting the above technical solution, the traction block at the bottom of the vibration plate can be wrapped by setting the buffer pad, reducing the collision between the traction block and the driven plate, and making it pull the vibration plate to reciprocate; the first shock-absorbing pad and the second shock-absorbing pad can reduce the damage caused by rigid contact when the impact block hits the buffer plate.

[0018] Furthermore, a heat sink is provided on the top of the circulating water tank, and a heat sink is provided on the outer wall of the heat dissipation water tank.

[0019] By adopting the above technical solution, heat can be dissipated during the operation of the equipment through the setting of the heat sink, and the water inside the circulating water tank and the heat dissipation water tank is dissipated to cool the internal hot water.

[0020] Furthermore, a sealing groove is formed on the outer wall of the clamping plate, and a sealing gasket is fixedly connected to the inner wall of the sealing groove.

[0021] By adopting the above technical solution, the gap between the clamping plate and the mold body can be filled by setting the sealing gasket, so as to prevent the artificial stone in a fluid state from entering the interior of the clamping plate through the gap, thereby affecting the use of the equipment or causing damage to the equipment.

[0022] The present invention has the following beneficial effects: 1. When the present invention is used, a suitable pressing plate is first replaced, and the pressing plate is driven by the press to move downward to form the artificial stone. When the pressing plate moves downward, it will push the clamping plate to move outward. At this time, the artificial stone is still a fluid. At this time, the artificial stone is extruded and formed by the pressing plate, and the heat is transferred to the mold body through the artificial stone to reduce its temperature so as to form faster. When the temperature of the mold body is too high, the water inside the circulating water tank will be used to cool it down, thereby ensuring a constant temperature and not affecting the forming speed of the artificial stone.

[0023] 2. The present invention starts a driving motor to make the vibration plate reciprocate, and the impact block repeatedly impacts the buffer plate through the reciprocating motion, and transmits the force to the inside of the mold body through the buffer plate. At this time, vibration can be performed, and the bubbles inside the artificial stone can be removed by vibration. The vibration generated by impacting the mold body can avoid the influence of excessive vibration on the molding of the artificial stone, and the vibration can be transmitted to the inside of the artificial stone more evenly through the mold body. After the vibration ends, the buffer spring will push it back to the original position to ensure accurate positioning of the pressing. The buffer spring can reduce the impact force of the impact, and can also follow the moving position when the pressing plate moves downward to more accurately position the pressing plate.

[0024] 3. In order to prevent the artificial stone from generating thrust on the clamping plate and thus affecting the molding of the artificial stone, the present invention has the following steps: when the pressure plate moves downward, it will come into contact with the moving block, and will squeeze the moving block to move toward the inside of the limit shell; the moving block and the driven connecting rod are hinged to enable the limit plate to move toward the outside of the limit shell; when the limit plate and the driven block are in contact, the friction force will prevent the movement of the driven block; since the driven block will move with the clamping plate, the movement of the clamping plate can be prevented when the movement of the driven block is prevented; when the pressure plate moves out, the moving block will be reset under the force of the reset spring, and will reset the limit plate, and the driven block will move with the clamping plate.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this embodiment, considering that only a small amount of small artificial stones are needed at the construction site, if a special shape is required, it is too wasteful to cut a large artificial stone. In the prior art, it is usually difficult to control the size of the artificial stone when molding the artificial stone. If a specific size molding is required, it is necessary to select a suitable mold and pressing plate first. Considering that the artificial stone production process needs to wait for solidification before it can be completely molded, the artificial stone will transfer heat to the equipment during the molding process, thereby causing the temperature of the equipment to rise. The increase in the temperature of the equipment will not only slow down the molding speed of the artificial stone, but may also cause the equipment to accumulate too much heat and cause damage; Before forming, it is necessary to replace a suitable pressing plate 13. After the replacement is completed, the pressing plate 13 is driven downward by starting the driving press 12. When the pressing plate 13 contacts the inclined surface of the clamping plate 21, the clamping plate 21 is squeezed outward, and the clamping spring 22 is charged. At this time, the artificial stone is still fluid, and the artificial stone will fill the gap. When the pressing plate 13 contacts the artificial stone, it will push the artificial stone and make the artificial stone further fill the gap, making the shape after pressing more regular. The pressing plate 13 needs to be pressed continuously during pressing until the artificial stone solidifies; when the artificial stone is still in fluid, the clamping plate 21 moves outward. During the movement, the triangular surface will contact the throttling block 23, so that the throttling block 23 moves along the oblique slide groove, thereby opening the water inlet. After the water inlet is opened, the water inside the heat dissipation water tank 26 will enter through the gap between the throttling block 23 and the circulating water tank 24. At the same time, when the water flow is too large, it can also enter the inside of the circulating water tank 24 through the through hole on the throttling block 23. In order to ensure pressure balance, the water inside the circulating water tank 24 will also enter the inside of the heat dissipation water tank 26. The hot water inside the circulating water tank 24 enters the inside of the heat dissipation water tank 26, which can increase the heat dissipation efficiency due to the larger area. Considering that some construction teams will not use artificial stones mass-produced by manufacturers in order to save costs or for the convenience of construction, but will produce them in large quantities on the construction site, the temperature of the equipment will gradually increase over a long period of time. High temperature can make the artificial stone made of cement solidify faster, but excessive temperature will cause damage to the equipment; since the press 12 will transfer heat to the mold body 1 during the artificial stone production process, when the mold body 1 is heated, it will exchange heat with the circulating water tank 24, and the water inside the circulating water tank 24 will be used to cool it down. When the temperature of the water inside the circulating water tank 24 increases, it will cause the water to expand due to the heat. After the water expands, the water pressure inside the circulating water tank 24 will increase, and the internal high-temperature water will be pushed out through the water pressure. The water inlet is transmitted to the inside of the heat dissipation water tank 26. When the internal temperature is too high, the impeller pump 25 can also be started to increase the efficiency of water exchange. When the amount of water in the heat dissipation water tank 26 increases, the pressure will also increase. Since the amount of water in the circulating water tank 24 decreases, the throttling block 23 will move along the oblique slide and open the water inlet to exchange water between the circulating water tank 24 and the heat dissipation water tank 26. Through the above operation, the equipment can be cooled during the artificial stone molding process. In the case that the temperature will not damage the equipment, the temperature can be used to accelerate the solidification of the artificial stone through the throttling operation. When the temperature is too high, the water exchange efficiency will be increased, thereby increasing the heat dissipation efficiency of the equipment. When the size of the artificial stone to be pressed is small, the distance between the pressing plate 13 and the clamping plate 21 is short. At this time, the cavity space between the clamping plate 21 and the mold body 1 will be larger. When the water in the circulating water tank 24 cools the artificial stone, the temperature will be transferred through the air in the cavity. Since the space in the cavity is large and there is more air, the internal temperature transfer is slow at this time. When pressing a larger artificial stone, the pressing plate 13 will further squeeze the clamping plate 21, making the space inside the cavity smaller. At this time, not only the water circulation in the circulating water tank 24 will be faster, but also the heat transfer of the air in the cavity will be faster. When the temperature of the equipment is too high, The water inside the circulating water tank 24 will increase the water pressure due to the high temperature expansion, and the increase in water pressure will cause the water to move into the heat dissipation water tank 26. At this time, the water inside the circulating water tank 24 will become less, and the throttling block 23 will also drop due to the reduction of buoyancy. The drop of the throttling block 23 will also make the water inlet larger, thereby increasing the water circulation efficiency. If the temperature cannot be lowered for a long time, the impeller pump 25 can be started to further increase the water circulation; the heat dissipation of the press 12 can be increased, and the excessively high temperature can be prevented from causing the artificial stone to solidify too quickly, resulting in an imbalance of internal and external pressures, thereby causing production quality problems such as cracks; When the artificial stone needs to be removed, the clamping plate 21 can be directly pushed outward to directly move the artificial stone out. Compared with the traditional mold, it can directly make room for gripping, so that personnel have a larger gripping area and also achieve the effect of convenient demoulding.

[0032] Specifically, the vibration mechanism 3 includes a driving motor 31, and the side of the driving motor 31 away from the mold body 1 is fixedly connected to the equipment body 11, and the output end of the driving motor 31 is fixedly connected to the eccentric wheel 32; an eccentric block is provided at the bottom of the eccentric wheel 32, and a traction link 33 is hinged on the outer wall of the eccentric block, and the eccentric block plays a positioning and limiting role for the traction link 33; a driven plate 34 is hinged on the inner wall of the end of the traction link 33 away from the eccentric block; a traction block is slidably connected to the inner wall of the driven plate 34; a vibration plate 35 is fixedly connected to the top of the traction block; the bottom of the vibration plate 35 is fixedly connected to a limit strip, and the limit strips are symmetrically arranged in two groups, and the adjacent sides of the limit strips are slidably connected to the two sides of the driven plate 34; the bottom of the mold body 1 is fixedly connected There is a sliding block; the bottom of the vibration plate 35 is slidably connected to the bottom of the inner wall of the equipment body 11, the top of the vibration plate 35 is slidably connected to the bottom of the circulating water tank 24, and the top of the vibration plate 35 is provided with a collision groove; the inner walls on both sides corresponding to the collision groove are slidably connected to the outer wall of the mold body 1, and the inner walls on the other two sides of the collision groove are fixedly connected with collision blocks 36, and there are multiple groups of collision blocks 36, and the same two sides of the collision groove and the collision block 36 are fixedly connected with buffer springs 37, and there are multiple groups of buffer springs 37, and the end of the buffer spring 37 away from the collision groove is fixedly connected with a buffer plate 38; a positioning groove is provided at the bottom of the collision groove, and the inner wall of the positioning groove is slidably connected to the outer wall of the sliding block; the side of the buffer plate 38 away from the collision block 36 contacts the outer wall of the mold body 1.

[0033] In this embodiment, considering that most of the existing technologies for removing bubbles use vacuum and vibration, although the effect of removing bubbles by vacuum is good, it is necessary to carry a vacuum machine, which is less convenient. At the same time, the vacuum treatment time is long and frequent maintenance is required. Most of the vacuum bubble removal is mass production in factories; the use of vibration bubble removal is inexpensive, convenient and fast, and more suitable for construction sites. The existing technology uses mechanical friction or vibration motors to directly impact the equipment to produce local stress. The uneven vibration may cause local long-term damage due to force, which may cause large vibration when the artificial stone is not completely solidified, and even cause the liquid artificial stone that is not completely solidified inside the artificial stone to shake, which may cause cavities inside the artificial stone, thereby resulting in poor production quality of the artificial stone; The eccentric wheel 32 is driven to rotate by starting the driving motor 31, and the eccentric block on the eccentric wheel 32 is hinged with the traction link 33 to pull the driven plate 34 to reciprocate. The driven plate 34 will move along the path of the limit bar, and the driven plate 34 is linked to the traction block to make the vibration plate 35 reciprocate. When the vibration plate 35 reciprocates, it will be limited by the positioning groove and the sliding block to prevent the mold body 1 from escaping or deviating. When the vibration plate 35 reciprocates, it will push the impact block 36 to repeatedly impact the buffer plate 38, and the buffer plate 38 will transmit the force to the mold body 1 and make the mold body 1 vibrate. The vibration of the mold body 1 will also be transmitted to the pressing plate 13. The vibration of the mold body 1 and the pressing plate 13 drives the artificial stone to vibrate synchronously, so that the bubbles inside the artificial stone can be discharged, and the uniformity of the vibration is also ensured. The impact force of the impact can be reduced by the buffer spring 37, and it can also follow the moving position when the pressing plate 13 moves downward to more accurately locate the position of the pressing plate 13. In the prior art, a vibration motor is used to vibrate the active pressure plate, or the eccentric force of the vibration motor is used to impact a part of the device to generate vibration; For example, in the prior art, a molding press for artificial stone manufacturing with publication number CN112873494A is provided with six groups of vibration motors on the top of an active pressing plate, and three groups of each perform centrifugal vibration in different directions to vibrate the active pressing plate. Since the vibration is transmitted from the top of the active pressing plate to the artificial stone, the generated vibration has a vibration effect on the top of the artificial stone, but the vibration effect on the other five sides of the artificial stone is weak, resulting in uneven vibration of the artificial stone. If the vibration motors are installed on the six sides of the equipment in order to make the vibration uniform, first of all, the number of vibration motors set on the six sides is a problem. If there are too few vibration motors, it may lead to ineffective vibration of larger artificial stones, and if there are too many vibration motors, it will be disadvantageous to energy conservation and emission reduction, and it will also lead to cost. The problem of increasing the height and difficulty in maintenance arises; secondly, when the six surfaces vibrate, if one of the vibration motors fails, it may cause uneven vibration, thereby causing the quality of artificial stone production to deteriorate. Since the equipment as a whole is vibrating, it is impossible to distinguish whether it is faulty during use; finally, since six sets of vibration motors are set, the energy consumption is large, which is not conducive to energy conservation and emission reduction; the present invention starts the drive motor 31 to make the buffer plate 38 impact the mold body 1 to generate vibration. The buffer plate 38 will diffuse the local impact to the whole mold body 1 to generate vibration, making the vibration more uniform. Using a single motor to drive the entire equipment is also conducive to energy conservation and emission reduction, and when the equipment fails, it can be found immediately, and even if the drive motor 31 fails, it will not cause uneven vibration; There is another vibration method in the prior art, which is to vibrate the equipment locally by using the eccentric force of the vibration motor, so as to vibrate the equipment simply and efficiently. However, local stress may be generated, and uneven vibration may cause local damage due to long-term force. It may cause large vibration when the artificial stone is not completely solidified, and even cause the liquid artificial stone that is not completely solidified inside the artificial stone to shake. It may cause cavities inside the artificial stone, resulting in poor production quality of the artificial stone. The present invention diffuses the local impact to the whole through the buffer plate 38, so as to make the vibration more uniform, so as to avoid the shape of the incompletely formed artificial stone changing during molding, thereby avoiding problems such as cracks during production.

[0034] Specifically, the limiting mechanism 4 includes a limiting shell 41, the outer wall of the limiting shell 41 is fixedly connected to the inner wall of the fixing groove, the inner wall of the limiting shell 41 is slidably connected to a moving block 42, the inner wall of the limiting shell 41 is slidably connected to a limiting plate 45, the inner wall of the limiting shell 41 is fixedly connected to a fulcrum shaft, and the inner wall of the limiting shell 41 is provided with a limiting groove; a return spring 43 is fixedly connected to the side away from the moving block 42, and the end of the return spring 43 away from the moving block 42 is fixedly connected to the limiting shell The inner wall of 41 is fixedly connected; a driven connecting rod 44 is hinged on one side of the moving block 42 close to the limiting plate 45; the inner wall of the driven connecting rod 44 at one end away from the moving block 42 is hinged to one end of the limiting plate 45; the inner wall of the driven connecting rod 44 is rotatably connected to the fulcrum shaft, and the inner wall of the limiting groove is slidably connected to the driven block 46; the outer wall of the driven block 46 is slidably connected to the inner wall of the limiting shell 41, and the side of each group of driven blocks 46 close to the moving block 21 is clamped with the side away from the clamping plate 21.

[0035] In this embodiment, it is considered that the size of the artificial stone can be controlled by squeezing the clamping plate 21 by the pressing plate 13. However, when the pressing plate 13 squeezes the artificial stone, the artificial stone may be squeezed out to both sides due to the force. At this time, a thrust may be applied to the clamping plate 21. When the clamping plate 21 is subjected to force, it will move outward. At this time, the artificial stone will flow to the gap, thereby causing the shape after molding to change, resulting in poor production quality.

[0036] In order to prevent the flowing artificial stone from generating thrust on the clamping plate 21 and affecting the molding of the artificial stone, when the pressing plate 13 moves downward, it will come into contact with the moving block 42 and squeeze the moving block 42 to move toward the inside of the limiting shell 41. The limiting plate 45 can be moved to the outside of the limiting shell 41 through the hinge connection between the moving block 42 and the driven connecting rod 44. When the limiting plate 45 and the driven block 46 are in contact, the movement of the driven block 46 will be prevented by friction. Since the driven block 46 will move with the clamping plate 21, the movement of the clamping plate 21 can be prevented when the movement of the driven block 46 is prevented. When the pressing plate 13 is moved out, the moving block 42 will be reset under the force of the reset spring 43, and the limiting plate 45 will be reset, and the driven block 46 will move with the clamping plate 21.

[0037] Specifically, a first ratchet is provided on one side of the limiting plate 45 close to the driven block 46 ; a second ratchet is provided on one side of the driven block 46 close to the limiting plate 45 .

[0038] In this embodiment, when the limiting plate 45 and the driven block 46 are in contact, the contact area is increased by the mutual engagement of the first ratchet teeth and the second ratchet teeth, and the driven block 46 is clamped by the characteristics of the ratchet teeth.

[0039] Specifically, the material density of the throttling block 23 is smaller than that of water, and the inside is hollow.

[0040] In this embodiment, the throttling block 23 has a density smaller than that of water and is hollow in design, so that when inside the circulating water tank 24, the throttling block 23 will be lifted up due to the buoyancy of the water. Since the throttling block 23 only achieves the throttling effect, the sealing of the throttling block 23 blocking the water inlet is not important. When the water inside the circulating water tank 24 decreases, the throttling block 23 will still be on the top of the water and achieve the throttling effect. Through throttling, the thermal expansion of the water inside the circulating water tank 24 can be realized to circulate the water.

[0041] Specifically, a buffer pad is fixedly connected to the inner wall of the driven plate 34, and there are two groups of buffer pads; a first shock-absorbing pad is arranged on the surface of each group of impact blocks 36 close to the buffer plate 38; a second shock-absorbing pad is arranged on the surface of the buffer plate 38 close to the mold body 1.

[0042] In this embodiment, the setting of the buffer pad can reduce the collision between the traction block and the driven plate 34, and make it pull the vibration plate 35 to reciprocate. At the same time, the incomplete wrapping design can reduce the vibration frequency, so that the next vibration will not occur immediately after the vibration ends. The inertia is used to vibrate the equipment, and the vibration from heavy to shallow can make the vibration more uniform. The first shock-absorbing pad and the second shock-absorbing pad can reduce the damage caused by rigid contact when the impact block 36 hits the buffer plate 38.

[0043] Specifically, a heat sink is disposed on the top of the circulating water tank 24 , and a heat sink is disposed on the outer wall of the heat dissipation water tank 26 .

[0044] In this embodiment, heat dissipation can be performed during the operation of the device by providing a heat sink, and the water inside the circulating water tank 24 and the heat dissipation water tank 26 is dissipated to dissipate heat and cool the internal hot water.

[0045] Specifically, a sealing groove is formed on the outer wall of the clamping plate 21, and a sealing gasket is fixedly connected to the inner wall of the sealing groove.

[0046] In this embodiment, the gap between the clamping plate 21 and the mold body 1 can be filled by the provision of a sealing gasket, thereby preventing the artificial stone in a fluid state from entering the interior of the clamping plate 21 through the gap, thereby affecting the use of the equipment or causing damage to the equipment.

[0047] When using, First, pour the artificial stone raw material into the interior of the mold body 1, start the driving motor 31 to drive the eccentric wheel 32 to rotate, and the eccentric block on the eccentric wheel 32 is hinged with the traction link 33 to pull the driven plate 34 to reciprocate, the driven plate 34 will move along the path of the limit bar, and the driven plate 34 is linked to the traction block to make the vibration plate 35 reciprocate, and the vibration plate 35 will be limited by the positioning groove and the sliding block when reciprocating to prevent the mold body 1 from escaping or deviating, when the vibration plate 35 reciprocates, it will push the impact block 36 to repeatedly impact the buffer plate 38, and the buffer plate 38 will transmit the force to the mold body 1 and make the mold body 1 vibrate, and the vibration of the mold body 1 will also be transmitted to the pressing plate 13, and the vibration of the mold body 1 and the pressing plate 13 will drive the artificial stone to vibrate synchronously, so that the bubbles inside the artificial stone can be discharged, and the uniformity of the vibration is also ensured, and the impact force of the impact can be reduced by the buffer spring 37, and the moving position can also be followed when the pressing plate 13 moves downward to more accurately locate the position of the pressing plate 13.

[0048] Secondly, before forming, it is necessary to replace a suitable pressing plate 13. After the replacement is completed, the pressing plate 13 is driven downward by starting the driving press 12. When the pressing plate 13 contacts the inclined surface of the clamping plate 21, the clamping plate 21 is squeezed outward, and the clamping spring 22 is charged. At this time, the artificial stone is still fluid, and the artificial stone will fill the gap. When the pressing plate 13 contacts the artificial stone, it will push the artificial stone and make the artificial stone further fill the gap, making the shape after pressing more regular. The pressing plate 13 needs to be pressed continuously during pressing until the artificial stone solidifies; when the artificial stone is still in fluid, the clamping plate 21 is pushed outward. During the movement, the triangular surface contacts the throttling block 23, causing the throttling block 23 to move along the oblique slide groove, thereby opening the water inlet. After the water inlet is opened, the water inside the heat dissipation water tank 26 enters through the gap between the throttling block 23 and the circulating water tank 24. At the same time, when the water flow is too large, it can also enter the inside of the circulating water tank 24 through the through hole on the throttling block 23. In order to ensure pressure balance, the water inside the circulating water tank 24 will also enter the inside of the heat dissipation water tank 26. The hot water inside the circulating water tank 24 enters the inside of the heat dissipation water tank 26, which can increase the heat dissipation efficiency due to the larger area. Considering that some construction teams will not use artificial stones mass-produced by manufacturers in order to save costs or for the convenience of construction, but will produce them in large quantities on the construction site, the temperature of the equipment will gradually increase over a long period of time. High temperature can make the artificial stone made of cement solidify faster, but excessive temperature will cause damage to the equipment; since the press 12 will transfer heat to the mold body 1 during the artificial stone production process, when the mold body 1 is heated, it will exchange heat with the circulating water tank 24, and the water inside the circulating water tank 24 will be used to cool it down. When the temperature of the water inside the circulating water tank 24 increases, it will cause the water to expand due to the heat. After the water expands, the water pressure inside the circulating water tank 24 will increase, and the internal high-temperature water will be pushed out through the water pressure. The water outlet is transmitted to the inside of the heat dissipation water tank 26. When the internal temperature is too high, the impeller pump 25 can also be started to increase the efficiency of water exchange. When the amount of water in the heat dissipation water tank 26 increases, the pressure will also increase. Since the amount of water in the circulating water tank 24 decreases, the throttling block 23 will move along the inclined slide groove, and the water in the circulating water tank 24 and the heat dissipation water tank 26 will be exchanged by opening the water inlet. Through the above operation, the equipment can be cooled during the artificial stone molding process, and when the temperature does not damage the equipment, the temperature can be used to accelerate the solidification of the artificial stone through the throttling operation. When the temperature is too high, the efficiency of water exchange will be increased, thereby increasing the heat dissipation efficiency of the equipment.

[0049] At the same time, in order to prevent the flowing artificial stone from generating thrust on the clamping plate 21 and affecting the molding of the artificial stone, when the pressing plate 13 moves downward, it will come into contact with the moving block 42 and squeeze the moving block 42 to move toward the inside of the limiting shell 41. The limiting plate 45 can be moved to the outside of the limiting shell 41 through the hinge connection between the moving block 42 and the driven connecting rod 44. When the limiting plate 45 and the driven block 46 are in contact, the movement of the driven block 46 will be prevented by friction. When the limiting plate 45 and the driven block 46 are in contact, the contact area is increased by the mutual engagement of the first ratchet and the second ratchet, and the driven block 46 is clamped by the characteristics of the ratchet. Since the driven block 46 will move with the clamping plate 21, the movement of the clamping plate 21 can be prevented when the movement of the driven block 46 is prevented. When the pressing plate 13 is moved out, the moving block 42 will be reset under the force of the reset spring 43, and the limiting plate 45 will be reset, and the driven block 46 will move with the clamping plate 21.

[0050] Finally, when the artificial stone needs to be removed, the driving press 12 is moved to the interior of the equipment body 11 through the sliding groove to make room for the artificial stone to be taken out, and then the clamping plate 21 is directly pushed outward to directly move the artificial stone out. Compared with traditional molds, space can be left for gripping, allowing personnel to have a larger gripping area and facilitating demoulding.
